Skid Resistance Value of Paving Hot Mix Asbuton with a Variation of Compacting Temperature

Abstract

Cold paving hot mix asbuton is a modified mixture of asbuton consisting of granular asbuton, aggregate, rejuvenating material, and additives mixed with hot and cold heat at 30°C. Asbuton cold paving hot mix asphalt is the latest modified asphalt from Asbuton, and it is necessary to do a cantabro test with the aim of the study being to determine the wear value on cold paving hot mix asphalt with variations in compaction temperature and immersion time. The study used variations in compaction temperature, namely 25°C, 50°C, 75 °C, and 100 °C, and variations in immersion time for 30 minutes, 24 hours, and 48 hours. The results of the optimum asphalt content obtained in the asphalt extraction test are 6,327%. The results of the wear value in a stable study for 500 revolutions were obtained at a solidification temperature of 100 °C, with results of 11,54% at a 30-minute soaking time, 14,93% at a 24-hour immersion time, and 13,63% at a 48-hour immersion time. The wear and tear has met the 2018 Bina Marga specification standard with a value requirement for wear, of 20%. Based on the results of tests carried out in the laboratory, it can be stated that in cold paving with hot mix asphalt, the compaction process should be carried out at a compaction temperature of 100 °C.
